GeForce RTX 3060 Ti vs Radeon RX 6800 XT

Intro

Compare those specifications to the Radeon RX 6800 XT, which comes with a GPU core clock speed of 1825 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also is made up of 4608 Stream Processors, 288 Texture Address Units, and 128 ROPs.

GeForce RTX 3060 Ti		(Unknown) MB/sec
	Difference: 524288 (-100%)

Texel Rate

The Radeon RX 6800 XT will be a lot (more or less 145%) better at texture filtering than the GeForce RTX 3060 Ti. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
GeForce RTX 3060 Ti		214320 Mtexels/sec
	Difference: 311280 (145%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6800 XT is superior to the GeForce RTX 3060 Ti, by a large margin. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce RTX 3060 Ti		112800 Mpixels/sec
	Difference: 120800 (107%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
